We are setting up a new linux box for Oracle, the following message appears when trying to create the dba group: [root]# groupadd -g 300 dba groupadd: group dba exists I've seen this before, but have no idea how this group was created. Typically I create dba with an id of 500, but this default group is usually some other ID IIRC. To answer some likely questions: * no, oracle has never been installed on this box * dba does not appear in /etc/group This is RH Linux EL4, kernel 2.6.9 Thanks, -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist
